No---not to us. The mark of the beast being the Pope has been around for centuries and first started by the Catholic priests themselves,
Pope Gregory I said: "I say with confidence that whoever calls or desires to call himself 'universal priest' in self-exaltation of himself is a precursor of the Antichrist."
and that was in AD 597!

Arnulf, archbishop of Reims disagreed with the policies and morals of
Pope John XV. He expressed his views while presiding over the
Council of Reims in A.D. 991. Arnulf accused John XV of being the Antichrist while also using the
2 Thessalonians passage about the "
man of lawlessness" (or "lawless one"), saying: "Surely, if he is empty of charity and filled with vain knowledge and lifted up, he is Antichrist sitting in God's temple and showing himself as God." This incident is history's earliest record of anyone identifying a pope with the Antichrist (see
Christian Historicism).

All the reformation priests said the same thing---such as Luther, Wycliff, Calvin. It is what all Protestants believed. That did not change until the Cathoilic church spent about 18 years coming up with Luis de Alcasars' version of interpreting Rev. during the counter reformation in the late 1500-1600's----You can look it up---it's part of History.
What is amazing is that today---most Protestants have forgotten all about their roots and started believing the Catholic version! And forgotten all about the many sects throughout history who kept the 7th day Sabbath centuries before there was an SDA, including the diciples. Not one verse in the bible says that Sunday wass kept by the dicipklesd as a day of worship. Only that they met oin that day---and breaking bread also meant "eating together" not just communion as it later became known as.
